复制代码 这里的expression是判断条件,和C/C++类似,CMake的条件也存在“与/或/非”以及“等于/大于/小于”等几种操作符,分别用AND/OR/NOT以及EQUAL/LESS/GREATER来表示。当判断条件为真,执行IF后的命令段,否则继续判断并执行相应条件对应的命令段,或者不执行任何操作。例如: 1. IF ( ${number} GREATER 4 ) ...
在了解 CMake 的基本概念和用法之后,作为一种编程语言,还是得从最基本的变量,流程控制(for 循环,if 条件),函数等开始学习。在最开始,我们强调一点——CMake 作为一门语言是区分大小写的!只是具体到通常使用的内置命令/自定义函数/自定义宏,不区分大小写。 不得不说,CMake 这一类文本化的语言语法都非常反人类...
cmake跟shell脚本很像,所有变量都是字符串类型,因此你可以看到这份代码的扭曲程度。 站内还有用CMake写红黑树的,感兴趣的读者可以自行搜索 计算math(EXPR <variable> "<expression>") 控制流if if(<condition>) <commands> elseif(<condition>) # optional block, can be repeated <commands> else() # optio...
This basically means if generator expression abc evaluates to true, then the value of the generator expression is xyz, otherwise it is an empty string. Let us take an example to make this clear. Save the following as CMakeLists.txt
If all OUTPUT and BYPRODUCTS paths are unique to each configuration (e.g. by using the $<CONFIG> generator expression), the first argument of COMMAND is still evaluated in the command config by default, while all subsequent arguments, as well as the arguments to DEPENDS and WORKING_DIRECTORY...
If COMMAND specifies an executable target (created by the add_executable() command) it will automatically be replaced by the location of the executable created at build time. (Use the TARGET_FILE generator expression to reference an executable later in the command line.) Additionally a target-...
全局生成器(Global generator):所有本地生成器共享一个全局生成器,后者负责监管构建过程,全局生成器由CMake本身创建并驱动。 CMake的执行开始时,会创建一个cmake对象并把命令行参数传递给它。cmake对象管理整体的配置过程,持有构建过程的全局信息(例如缓存值)。cmake会依据用户的选择来创建合适的全局生成器(VS、Make...
PS:官网教程中还有剩余几步,但笔者感觉好像没有什么用…… 所以就写到这里好了。注:略去的几步: 4、添加系统内省(Adding System Introspection) 5、添加已生成文件和生成器(Adding a Generated File and Generator) 6、构建一个安装程序(Building an Installer)...
generator-expression定义为$<...>的形式。该表达式的值有多种形式,而且支持嵌套使用: 条件表达式 $<condition:true_string>当条件为1时,表达式为true_string,否则为空 $<IF:condition,true_string,false_string>当条件为1时,表达式为true_string,否则为false_string ...
